Dr. Ahmed Al-Rubie

Dentist  |  BDS (SHEFFEILD)

I qualified from Sheffield in the UK! I really enjoy the challenge that comes with being a Dentist, as well as meeting the variety of characters and personalities that the job brings with it. I’m passionate about doing my best for my patients and providing a comfortable experience for those in my care, particularly those who are anxious or nervous. I will take my time explaining any diagnosis’, treatment options and potential risks involved in procedures to help you make an informed decision about your care. Nothing gives me greater pleasure than helping to bring a lost lost smile back to a patients face!

In my spare time I love hiking, camping and youth work and have put these passions of mine into one by volunteering as a scout leader! I love an adventure and have come to really appreciate the beauty of not only the landscape, but also the sea. Learning how to dive underwater recently has given me a new perspective of nature and I cannot wait till my next diving voyage!
